Ever since I got this Gigabyte GTX 750 Ti video card, it's had red lines all over the screen as is it was repeating exclamation points or semicolons. Even after I added the driver it seemed fixed until I rebooted. How do I get these off or check if I installed the software correctly?

Turns out I installed the driver incorrectly, I found the following procedure to repair:

From the grub menu>advanced settings>recovery mode, then after a loading screen pick root.

cd /

to enter the main directory

sudo fsck -Af -M

to fix a disk error preventing me from editing files with a read-only error

mount -o remount /

to reload

rmdir -rf tmp

to delete the folder where it was trying to save but couldnt, then go run the driver

cd home/(user name)/Downloads

to get into the directory

./(filename)

it should recreate the directory and install correctly, if not just do

cd /

and

mkdir tmp

Before you dive into the driver, you need to prove the hardware is good. First, take the card out and plug it back in to eliminate a seating problem. Make sure the power cable is disconnected from the PC and take ESD precautions. If that doesn't help, continue. From the manufacturer web site it appears to be a GV-N75TOC-2GI, for which there was a BIOS update released on June 4th 2015. You could get the latest firmware, if it's not at version fd0, and install it (you will need to do this natively in Windows (ie not under VM). You could also run a GPU test - I use GPUTest from . You could start off by running the test if you prefer.
